'certain-new and useful Improvements in Holsters, of which the following is a full, clear, and exact descri tion, such as will enable others skilled in tie art; to which it ap pertains to lmake and to use the same, reference being had to the accompanyine drawings, which illustrate the preferred orm 4of the invent-ion; though it is to be understood that the invent-ion is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is an end view of a ear underframe 'comprising longitudinal wood sillswith my improved bol ster. Fie'. 2 is an inverted lan view of the bolster. llig. 3 is a sectiona view of the bolster, the section being taken on line 3-8 of Fig. i?. Fig. 4 is a sectional view of the bolster, the section being taken on line l-4 of Fig'. 2. Fig. 5 is an elevational View looking at the bolster as from the side of the car.

The object of the invention is to )rovide a cast holster comprising an integral structure with parallel sill supporting members provided with sill seats combined with diag# onally disposed supporting' membersI which are also provided with sill seats and side bearings which extend between said diagonally disposed su )porting members. the bolster body beingr also prorided with openings through which may' be pro'ected metal draft sills which extend in a ower plane' than the wood longitudinals.

le'ierrin Y bearing wit i'a center pin socket 2 extending vertically 'throuefb the body portion of the bolster, as best s iown in the sectional riew 3 for said socket extending from the center l llange 4 of the' bolster, which llauo'e is of considerable area. and is duplicatedhon' the under side, ol' the. bolster, as shown in the inverted view Figi 2, the lower -tlange being indicated bj' the reference numeral 5.

lflxtcndiincr longitudinally of the underframe are parallel ribs or armsl 6 shown iu there being sill seals 7 formed on thefe'iids ot' said members 6,

saidpsill seats formin extensions of the upper flange l of the bolster and being in substantially the plane thereof.

lxtendixngr obliquely outwardly from the members ti are armsl il, shown in dotted lines in said Fig. L. and these arms` t) are likewise provided with sill seats T, which are praccontintmtionsl of the said upper tically flange l.

Arranged vin the arc of a circle struck from the center bearing are side bearings l0 'which serre as connectors for the obliquely disposed arms il, v aid sido laairingsnbein provided with bottom tlanges llnltl-e'xe' tend to a plane lsomewhat below the bottom flange 5 ol' thev bolster trurtnre for well understoml purposes.

The sill seats i' are provided with reinforeinf?r ribs la which intersect the arms 9 extending under l aid `sill seats and with lian res Tb which extend at subs-tantndlr-right angles from the armsl t3 before referred to.

The draft. sills 12% shown in Fig'. l extend through the o )citings Il at cach side ot' the eenter pin soc (et and .said draft sills may be formed of any desired sha ie and connected tothe .bolster if desired.. either b \""riveting to the top flange l.or to the perimclriral "flanges lnand for that-purpose flanges 15 may be caused to extend to any desiredextent beyond the centrali),` disposed webs lli of the bolster either fm-wardly or rearwardly thereof, .or both forwardlwl and rem'wardly, l as mayv bc desired. 1, 'lhe flanges ^lare considerably wider i than the arms t-h and the 'upper flange 4: forms inell'cc' a platform upon which rest the wood longitudinal.` l?. l What l claim is: l i. ln a cast bolster` diaironally disposed -mcmbers withsill seats, .side bearings betwccu `said diagonally disposed members, and parallel sill supporting members ex-` tendiner latm'all)y from the diagonal mehr bers.
